Yes, Mia Lou can cover white/gray hair. Mia Lou is a permanent hair color that penetrates the interior of the hair.
The product opens the hair scales and transforms the natural melanin pigments into water-soluble molecules.
Through the action of the alkalizing agent, the oxidizing agent releases oxygen, which transforms the color formers inside the hair into dyes. The scales close and the colored pigments remain trapped in the core of the hair fiber.
The color result? Permanent coloring makes it possible to dye your hair to your heart's content in any shade you want: lighter, in the same tone, darker, with highlights. It is also the only coloration that provides up to 100% gray coverage. The effect is more than permanent: the hair color lasts and a root is created. (hair grows back)
